It's Kay's fault that they died.
It is the fault of Dr Kay Morgan that anyone who was killed by the white pointer in the park died.
She was the one who wanted the park to have "the only living white pointer in capivity" and pointed that no-one had done it before.
The reason that no-one had done it before, you blond bint, is that white pointers are dangerous and few know how to handle them.
You would think that, with her training, she would know that.
